Another possibillity is that the water pump is no longer functioning.

This also creates air pockets which can make the temp gauge quickly jump or fall.

Thus, the temperature gauge on your dashboard is your window into the coolant temperature as seen by the temperature sending unit.

Why does my Honda engine overheat while driving?
If that doesn’t help you may want to have the water pump checked. The impeller blades could have disintegrated after so many years.
